This is probably a bad photo to post, as I can't for the life of me remember the occasion of Stephen Bornhoft's visit, but in any case he is Stewart's nephew and godson, and they are standing on top of Mt. Soledad in San Diego in 2011. The group of buildings behind Stephen's head is not downtown San Diego, but an archipelago of buildings in the University Town Center area just east of La Jolla. Like Stewart, and Stewart's sister and brother, Stephen is an engineer who currently lives in Salt Lake City, doing wonderful things in the medical device industry.
And yes, San Diego is usually this sunny, and this warm.
